Sewage treatment has evolved a lot throughout the ages, and now most new communities have state of the art sewage systems, with every house connected by pipes to a treatment center, which goes via the sewage and cleans it up, before sending it back down river. But not everybody is connected like this, and there is many homes, buildings and communities that do not have a direct connection to a municipal system. In a case like this, usually they will use septic tanks.
The earliest types of sewage systems was to simply make digs in the field, and sometimes on the side of the roads in urban areas, where people would deposit their trash and excrement, to be brought down by the rain towards a source of water. It was unbelievably insoluble and dirty. It quickly had become the source of many diseases, in addition to being very smelly. It didn't take long for individuals to realize the advantages getting that stuff under ground, inside a special container. This is what a septic tank basically is.
Generally, a huge container, set into the ground, with pipes carrying sewage connecting into it. According to the size, it can serve a single house, or even a whole community. Then, now and again, a truck comes in and sucks everything inside the tank up to the truck, before sending it up to a treatment center. It's a way to have a sewage system that works, without being connected to a treatment center directly, either because the building is far from town, or within a closed community.
A modern septic tank usually has several levels. At the bottom, you find the sediment, together with the surface scum at the top. The inlet for the pipe is usually in between both, and the top of the tank is where the hatch is. Some septic tanks even have an hybrid system, where the top section is sent out via other pipes to irrigate fields, or just simply down onto vast plains to evaporate. It is a concept that was fairly popular on farms, and can save a great deal of money, although it's not always environmentally friendly. The septic tank itself is normally made of metal, and has to be surrounded by a cement exterior. Laws for such tanks have become more severe during the past few decades, due to the fact that a leaking tank can cause major problems to the environment. It may also infect freshwater supplies, which can be bad for humans and animals. Sediment also produces a amount chemicals, that can easily be dangerous.
Overall, a septic tank is a way to get your sewer system in balance when you have no other choice, but life of today is more preferable served with a good municipal system, where excrement does not have to be stored and sent by truck, instead everything is connected and sent off directly. You finally saving a lot of potential issues. Still, it is really not always possible, and as a result septic tanks still play a role even today.
